Re: 3400 Ford Power Steering Question

The upper and lower thrust bearing almost never go bad on a PS unit as they are constantly bathed in oil.I'll bet you dollars to doughnuts that you either forgot or improperly swedged the upper nutto the shaft and it loosened on you.

Well I just repaired the leak with a quicky sleeve and didn't tear into the valve body or the housing but I guess I'll find out if the nut is loose when I get in there to see what's going on. I just hate that I have to tear it all apart again after having spent 11 months fixing leaks, finding salvage parts and rebuilding parts and trying to get the thing in a usable condition. I enjoyed the challenge at first cause I like working on mechanical things but I've had as much fun as I can enjoy on this project. If I didn't have twice as much invested as buying a new one I would sell it but I'm in to deep to back out now. Thanks for letting me know where to look for the problem.

Yeah, the worst part about it is pulling the tin off again.If it were me and I was that far into it I would go ahead and pull the hydraulic block out of it and go through it. Take it apart and clean the rust and crud out of it. I like to wash fine parts like that in lacquer thinner then lightly grease and reassemble. Replace the lower seal while you are in there and both of the Orings - part #s 14 and 33 in the photo below.Make sure you clearly mark the lines to the cylinders at they can be a pia to sort out if you don't. I use tape and mark them top and bottom.Be careful not to drop the little springs and plungers in the hyd block as you pull it off the column. They will want to fall out the bottom.I&T FO-31 manual has a pretty good description of adjusting the spring washer and swedging the nut.If you get into trouble reinstalling the plungers, etc in the right holes just holler.We can help.
